Advances in molecular genetic tools enable this, even for cryptic species complexes that are often morphologically confusing or indistinguishable. However, the costs of these methods and sequencing remain prohibitive for many researchers, particularly in less developed regions. The aim of this study was to test whether ISSR-PCR markers can be used to distinguish three similar horseshoe bat species that are often misidentified and occur in sympatry in Serbia. Samples from 64 Rhinolophus euryale, R. blasii, and R. mehelyi bats were identified using this ISSR-PCR approach, and species identifications were additionally confirmed by sequencing D-loop fragment of mitochondrial DNA. ISSR-PCR yielded species-specific band patterns on the agarose gel that allowed the differentiation of three medium-sized horseshoe bat species. This approach does not require sequencing, making it a quick and inexpensive tool for the genetic identification of these species, and complements already existing methods. There is potential to scale up this method to other cryptic species complexes, reducing misidentifications that lead to inaccurate population trend assessments and have knock-on effects on our ability to monitor and conserve wildlife, especially rare and endangered species.","PeriodicalId":56073,"journal":{"name":"Mammal Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139414648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A close look at the literature indicates that fishing cats are piscivorous; however, this is based on very few studies. Understanding the patterns of resource utilisation by species is crucial for assessing their role in ecosystems and in ensuring their conservation. Therefore, our study presents insights into fishing cat feeding patterns from mangroves of the Godavari delta, Andhra Pradesh, India. We collected 303 putative fishing cat scats and conducted diet analysis using 120 genetically identified scats. Our analysis revealed that fish was the most important prey for fishing cats in the study area (61.6% in frequency of occurrence), followed by crabs (30%) and rodents (28.3%). The prey composition did not vary significantly between the three seasons but there were differences between the survey years. The niche breadth also varied across the three seasons, with lowest niche breadth estimated in summers (0.36) with highest contribution of fish in the diet and highest in winters (0.75) probably due to increased contribution of other prey items along with fish. Our results suggest that long-term conservation and survival of the fishing cats depends on fish populations, which are the main prey of the species and thus recommend the need to protect the fish populations in the Godavari delta and the surrounding riverine habitats. Given the importance of fish to the diet of the fishing cat, the health of waterways throughout their distribution must be one of the focal strategies of conservation action.","PeriodicalId":56073,"journal":{"name":"Mammal Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139079886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected GPS telemetry data from 93 opossums in a rural, non-agricultural landscape in South Carolina, USA (2018–2019) to examine factors influencing space use and resource selection. Estimated male home ranges (99% utilization distributions) were on average 50% larger than those of females (mean home range 115.9 ± 103.7 ha vs 76.7 ± 75.0 ha). The home range size decreased on average by 20% with each 20% increase in deciduous land cover but was not affected by season or other landscape factors. Core area sizes (65% utilization distributions) were not influenced by sex (mean core area size 29.1 ± 23.7 ha and 22.4 ha ± 13.8 for males and females, respectively) or season, but the core area size decreased by 14% with each 400 m increase in distance from a permanent water source. Resource selection by opossums primarily occurred at the landscape level. Both males and females generally selected for wetlands while avoiding pine forests and developed/open areas, likely the result of differences in resource availability and predation risk between habitats. Opossums also tended to select for linear features such as unpaved roads and edge habitat, which may facilitate movement across the landscape. The home ranges we documented are among the largest recorded for opossums in the USA, likely the result of the relatively low resource abundance throughout our study area due to comparatively minimal anthropogenic influence.","PeriodicalId":56073,"journal":{"name":"Mammal Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138821675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Australia’s ecologically and culturally significant ghost bat (Macroderma gigas) has suffered substantial population declines, in part due to disturbance and loss of roost sites. This sensitivity poses impediments to studies of the ghost bat’s ecology and behaviour, which in turn inhibits evidence-based conservation and management of the species. We used full-spectrum acoustic playback, in combination with thermal video recordings and netting, as a novel method to investigate the behavioural ecology of this enigmatic bat. We tested whether ghost bats are responsive to conspecific social vocalisations and, if so, whether responses differ according to signaller and receiver characteristics. Individuals were attracted strongly to two of four vocalisation types, and responses depended on sex, thus providing the first experimental evidence that the ghost bat’s complex vocal repertoire has multiple functions. Responses did not differ with geographic location, indicating that our method can be used across the species’ range. We discuss how full-spectrum acoustic playback helps improve our knowledge of the behavioural ecology of this species and highlight the applicability of our methods for targeting specific conservation needs in bats.","PeriodicalId":56073,"journal":{"name":"Mammal Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138520299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of 301 scats was performed in order to study the diet of cats in a National Park in the alpine ecosystem of an oceanic island (Tenerife, Canary Islands). The results were compared with those obtained 35 years ago. In this study, eight types of vertebrates were detected in the cat diet: two endemic reptiles, four introduced mammals, and two birds. Although introduced rabbits were the most important prey, accounting for 53.9% of the biomass in the diet, this figure is among the lowest recorded in the Canary Islands. Data show a shift from the diet 35 years ago, with a decrease in the percentage of rabbits consumed, from 73% of diet biomass in 1986 to 53.9% today, and an increase mainly not only in reptiles but also in native birds. This change is due to a decrease in the rabbit population, probably motivated by the incidence of haemorrhagic disease (RHDV2). Using a daily intake of 170 g, we estimated that a single cat could prey on 1331 vertebrates/year. Assuming a low cat density of 1 cat/km2, the total cat population in the National Park would kill 257,739 vertebrates, being native species particularly vulnerable to predation, with 166,249 reptiles and 5588 birds annually. Thus, with the aim of updating and improving management strategies for the conservation of native biodiversity, there is a need for new research on invasive predators on islands where diet may change over time.","PeriodicalId":56073,"journal":{"name":"Mammal Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138520294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bioacoustics has long been employed to study wolves and coyotes, but the process of extracting relevant signals (e.g., territorial vocalizations) from large audio datasets remains a substantial limitation. The BirdNET algorithm is a machine learning tool originally designed to identify birds by sound, but it was recently expanded to include gray wolves (Canis lupus) and coyotes (C. latrans). We used BirdNET to analyze 10,500 h of passively recorded audio from the northern Sierra Nevada, USA, in which both species are known to occur. For wolves, real-world precision was low, but recall was high; careful post-processing of results may be necessary for an efficient workflow. For coyotes, recall and precision were high. BirdNET enabled us to identify wolves, coyotes, and apparent intra- and interspecific acoustic interactions. Because BirdNET is freely available and requires no computer science expertise to use, it may facilitate the application of passive acoustic surveys to the research and management of wolves and coyotes, two species with continental distributions that are frequently involved in high-profile and sometimes contention management decisions.","PeriodicalId":56073,"journal":{"name":"Mammal Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138520296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
